Probably the correct choice bro. I just have a feeling this is one of those sour deals. The seller has been selling cheap crap to build up his or her rep and then hit a ton of people for a shit load of money and disappear. ES chips, or Engineering Samples, are actually the property of Intel. Intel "loans" these chips out and if the person sells said ES chip it is then considered theft according to Intel's rules. LOL, even though millions of these are and have been sold. I currently have a Xeon W3520 that is a damn ES chip. Purchased a motherboard and chip over a year ago and it was in the board. Sucks because legally a person can't even sell it.
